San Mattia alle Grazie or San Mattia was a church dedicated to Saint Matthias on via delle Grazie in Brescia, Italy, between the corso Garibaldi and the church of Santa Maria delle Grazie - it was named after that church, but they were never otherwise linked. It was founded between 1250 and 1300 and was suppressed in 1797 after the French invasion. It now houses the gym for the neighbouring secondary school.
